Both species remembered where food was hidden better if they saw a human hiding it than just by relying on scent alone.
in Ernstbrunn, Austria. They tested the ability of each animal to find four, six, or eight caches of food, after either seeing a human hiding them or without seeing the food be hidden.
They found that both dogs and wolves found more of the first five food caches more quickly and with less distance traveled if they had seen the food compared to scenarios where they didn’t observe a human hiding the cache. The authors believe that this suggests that the wolves and dogs didn’t just use their noses to find the treats and provides more support to the theory that wolves and dogs are capable of observational spatial memory.
“While domestication probably affected dogs’ willingness to adjust to humans, the results of the current study collaborate previous findings suggesting that cognitive abilities do not differ very much between dogs and wolves,”
